LX570_OM_OM60L21U_(U) Minimum projected turning circ le & projected course line
Use the minimum projected turn-
ing circle & projected course line
(when displayed) to check the
vehicle’s path with relation to
obstacles. If the minimum pro-
jected turning circle line (blue) is
over the obstacle as shown in the
illustration, or the obstacle falls
within the minimum projected
turning circle, if you turn with the
minimum possible turning circle,
the vehicle may collide with the
object. When the projected
course line (yellow) is displayed,
be sure to operate the steering
wheel so that the obstacle stays
outside the projec ted course line
until the vehicle has passed the
object.

If the battery is disconnected and
connected again, the message
“System initializing” will be dis-
played on the screen. The help
screen appears when “?” is
touched. Make a correction using
the following method in accor-
dance with the display.
Carry out one of the following.
• When the vehicle is stopped,
turn the steering wheel all the
way to the left, then all the way
to the right.
• Drive for at least 5 minutes on a
road with as few turns and
curves and as little heavy traffic
as possible.
When the screen returns to the
original display, correction is com-
plete.
If the above screen remains, have
the vehicle inspected at your

When a solid object is close by
■
When using the wide view front & side monitor
Even if an obstacle is no longer visible on the side monitor, do not turn the steering
wheel further in the direction the vehicle is turning until the vehicle has moved com-
pletely past the obstacle. If the steering wh eel is turned to full lock, the vehicle will
turn in the smallest possible turning circle, and may collide with the obstacle. The screen’s guide lines are designed for level
surfaces (road surface etc.) or flat walls etc.
When driving near the obstacle, the obstacle
may be displayed as outside the projected
course line, and it may seem that there is no
danger of a collision, however any sections
protruding from the wall may project over the
course line and the vehicle may actually col-
lide with the obstacle.
In cases such as this were the projected
course line passes clos e to obstacles, always
visually check the surroundings for safety.

In the following cases the 4-Wheel AHC will not operate ●
The brake pedal has been depressed for a few seconds or longer while the vehi-
cle is stopped. ●
Vehicle height control has not been frequently used. ●
The suspension fluid temperature is lower than -22°F (-30°C). ●
There is ice on the suspension. ●
Driving on bumpy roads which may cause the suspension to fully elongate. ●
If the steering wheel is abruptly turned more than 3/4 of a revolution with the
center differential lock system activated.■
Cold weather operation
It may take longer for the vehicle height to change if the suspension fluid tempera-
ture drops below 5°F (-15°C).
The 4-Wheel AHC does not operate when the suspension fluid temperature drops
below -22°F (-30°C). ●
In this case, even if the height select switch is pressed, the vehicle height will not
change. Once the vehicle has been driven for a short time and the suspension
fluid has been warmed to within normal operating limits, the 4-Wheel AHC will
begin operating and the vehicle height wi ll automatically change to the selected
mode. ●
When the suspension fluid is around -22°F (-30°C), the vehicle height may not
be able to be raised, even if the 4-Wheel AHC is operating. In this case, pull the
height select switch to “ ” then push to “ ” after driving for a short time longer
to select the desired vehicle height.■
Parking and stopping tips ●
If you immediately stop the engine after off-road driving, the vehicle height may
gradually lower. When parking, make su re there is nothing under the vehicle
that may come in contact with the underbody. The vehicle will return to the set
height when the engine is started. ●
The vehicle height may change as the temperature changes when the engine is
stopped. The vehicle will return to the set height when the engine is started.

When driving
LX570_OM_OM60L21U_(U) Driving assist systems To help enhance driving safety and performance, the following systems
operate automatically in response to various driving situations. Be aware,
however, that these systems are supplementary and should not be relied
upon too heavily when operating the vehicle.
■ Multi Terrain ABS (Anti-lock Brake System) Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface, or in off-
road conditions (such as rough roads, sand and mud).
■ Brake assist Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
■ VSC (Vehicle Stability Control) Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces.
■ Active TRAC (Traction Control) Helps to maintain drive power and prevent the 4 wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■ Hill-start assist control Helps to prevent the vehicle from rolling backwards when starting on an
incline or slippery slope.
■ VGRS (Variable Gear Ratio Steering) Helps to adjust the wheel turning angle in accordance with the vehicle
speed and steering wheel movement.
■ PCS (Pre-Collision System) (if equipped) P. 3 5 5
